BACKGROUND OF THE INVENTION

The following includes information that may be useful in understanding the present invention(s). It is not an admission that any of the information provided herein is prior art, or material, to the presently described or claimed inventions, or that any publication or document that is specifically or implicitly referenced is prior art.

1. Field of the Invention

The present invention relates generally to the field of snow blowers and more specifically relates to a snow blower sled accessory.

2. Description of the Related Art

During the winter months, many people in modern societies can be found outside of their home, office, or apartment, laboriously using a shovel to remove snow from their driveways and walkways. The local government may send a truck to plow the streets and apply salt to icy areas, but this does not solve the problem of clearing snow from one's front door to the shoveled streets or sidewalks. The task of removing accumulated snow from driveways, walkways, and sidewalks historically have required hard manual labor by way of using a snow shovel to scoop, lift, and heave the snow to the sides. In addition to shoveling snow, retail businesses may be faced with the added task of shoveling sand or snow on storefront sidewalks to afford traction for pedestrians and consumers, safeguarding them against injury due to slipping.

These types of shoveling tasks are physically demanding and may even be dangerous to individuals who are elderly or who are not physically fit. To avoid the hassles of a shovel, many individuals purchase and employ snow blowers. A snow blower is a machine for removing snow off the ground and is typically used to clear snow from driveways, sidewalks, roadways, paths, runways, railroad tracks, and the like. Snow blowers may operate on either electric power or a gasoline or diesel engine to throw snow to another location. Snow blowers are a useful electric or gas operated power tool in assisting land owners and occupiers in clearing snow off their property quickly and efficiently while expending less energy than using a conventional snow shovel. Furthermore, an individual who wishes to clear snow off their land has less risk injuring their backs, knees, and wrists while using a snow blower as opposed to a shovel. However, as convenient as snow blowers may be, individuals may encounter difficulties when a snow blower is used on unpaved or graveled surfaces, whereby the low-lying blower tends to “dig” into the ground surface, resulting in marred driveways and paths as well as picking up gravel which may damage the snow blower blades.

Various attempts have been made to solve the above-mentioned problems such as those found in U.S. Pat. Nos. 4,441,266; 6,508,018; and 2004/0205985. This prior art is representative of snow blower elevating accessories. None of the above inventions and patents, taken either singly or in combination, is seen to describe the invention as claimed.

Ideally, a snow blower sled system should be convenient in use and, yet, would operate reliably and be manufactured at a modest expense. Thus, a need exists for a reliable universal snow blower sled system to attach universally to walk behind snow blower machines and to avoid the above-mentioned problems.

BRIEF SUMMARY OF THE INVENTION

In view of the foregoing disadvantages inherent in the known snow blower, the present invention provides a novel universal snow blower sled system. The general purpose of the present invention, which will be described subsequently in greater detail is to provide greater convenience of use and protection of the snow blower machine.

Disclosed herein is a universal snow blower sled system with at least one but preferably two skid devices held thereto by at least one attacher which may be bolt fasteners, but in some embodiments, could be a shaft with through-hole wherein a ring-pin may be inserted through the shaft and biasly coupled. The skid device(s) preferably removably attach to a bottom portion of a snow blower machine such that a rotary auger within the snow blower machine is substantially prevented from contacting a hard planar surface thereby preventing damage to the rotary auger which displaces snow located on the hard planar surface (the ground, driveway or the like.) This is accomplished by the skid devices maintaining a clearance-distance of at least the thickness of the skid device (shims may also be used). The skid device(s) further comprise at least one hole wherein the attacher is removably insertable through the hole(s) in the skid device and through hole(s) in the housing of the snow blower machine such that the skid device(s) is/are removably attached to the snow blower machine.

The skid device is attachably mounted to the housing such that the length of the skid device(s) runs parallel and adjacent to an outer edge of the housing. The skid device(s) run parallel with the drive-wheel system of the snow blower machine and have a length greater than the width, having a perpendicularly-oriented outside planar edge-wall, and an upturned front surface (ski-profile). The skid plate may have a back surface with no end-wall such that snow is not collected on the skid plate when the snow blower machine is in motion. The up-turned front surface allows the snow blower machine to ride on top of a hard packed snow or the ground surface and act as a ski device. The skid device may comprise aluminum, a ferrous material, or a composite material resistant to brittle fracture.

A method of use for a universal snow blower sled system may comprise the steps of: positioning at least one skid device adjacent to the snow blower machine; (removably) attaching the at least one skid device to snow blower machine using at least one suitable attacher; using the snow blower machine with the universal snow blower sled system attached for removing snow and optionally, removing snow blower sled system, if desired by the user, and storing the snow blower machine and snow blower sled system for a future use (separately or together—installed.)

The universal snow blower sled system may be manufactured as a kit including at least one skid device; at least one attacher; and a set of user-instructions for installation and use of the universal snow blower sled system.

The present invention holds significant improvements and serves as a universal snow blower sled system. For purposes of summarizing the invention, certain aspects, advantages, and novel features of the invention have been described herein. It is to be understood that not necessarily all such advantages may be achieved in accordance with any one particular embodiment of the invention. Thus, the invention may be embodied or carried out in a manner that achieves or optimizes one advantage or group of advantages as taught herein without necessarily achieving other advantages as may be taught or suggested herein. The features of the invention which are believed to be novel are particularly pointed out and distinctly claimed in the concluding portion of the specification. These and other features, aspects, and advantages of the present invention will become better understood with reference to the following drawings and detailed description.

DETAILED DESCRIPTION

As discussed above, embodiments of the present invention relate to a snow blower skid device and more particularly to universal snow blower sled system 100 as used to improve the protection of the snow blower machine 110 while reducing maintenance and repair costs and adding convenience for its user(s).

Referring to the drawings by numerals of reference there is shown in FIG. 1, a perspective view illustrating universal snow blower sled system 100 installed on snow blower machine 110 according to an embodiment of the present invention.

The primary object of universal snow blower sled system 100 recognizes a need for a sled system that may be mounted to a conventional snow blower machine 110 to provide an elevated snow surface attack for snow blower machine 110 while in use. Universal snow blower sled system 100 may preferably comprise a pair of skids 120 with screws and bolt fasteners 135 such that skids 120 may be mounted to the bottom of each side of a snow blower auger housing. Universal snow blower sled system 100 may comprise at least one skid(s) 120 device and at least one attacher 130 used to removably attach skid(s) 120 to a bottom portion of snow blower machine 110 such that rotary auger 112 within snow blower machine 110 is effectively prevented from contacting hard planar surface 140.

At least one but preferably two attacher(s) 130 are used to removably attach at least two skid(s) 120 to bottom portion of snow blower machine 110 such that rotary auger 112 is able to rotate and displace snow located on hard planar surface 140 while maintaining a suitable clearance-distance of rotary auger 112 from hard planar surface 140. In this way the present invention serves to prevent rotary auger 112 from contacting loose debris (pebbles, sharp concrete edges, etc.) often found on the ground, cement pad, sidewalk or other.

Referring now to FIG. 2, a perspective view illustrating universal snow blower sled system 100 installed on snow blower machine 110 according to an embodiment of the present invention of FIG. 1. Skid(s) 120 is/are preferably attachably mounted (suitably affixed) to housing 150 such that length of Skid(s) 120 run parallel and adjacent to an outer edge of housing 150 and run parallel with a drive-wheel system of snow blower machine 110. Skid(s) 120 elevate snow blower machine 110 so that damage is suitably prevented to rotary auger 112 by contacting gravel or hard rock surface(s).

Referring now to FIG. 3, a perspective view illustrating an inner side view angle of the device according to an embodiment of the present invention of FIG. 1.

Universal snow blower sled system 100 comprises at least one skid(s) 120 having a length and a width such that the length is greater than the width and may further have two skid(s) 120 of equal size that may preferably resemble the shape of runners on a sled or that of skis (ski-profile) measuring approximately 10″ in length, 2″ in height, and 3″ in width. Skid(s) 120 functions as a ski to displace obstacles when moving in a forward direction and further may comprise perpendicularly-oriented outside planar edge-wall 160 to provide structural support for skid(s) 120 in some embodiments. Typically skid(s) 120 are constructed of a metal or other suitably durable material. Skid(s) 120 (acting as a skid-plate) may comprise an upturned front surface and a back surface with no end-wall such that snow is not collected on upper surface of skid plate 170 to minimize corrosion. The upturned front surface 175 allows snow blower machine 110 to ride on top of snow located on hard planar surface 140.

Referring now to FIG. 4, a perspective view illustrating an outer side view angle of the device according to an embodiment of the present invention of FIG. 1. Skid(s) 120 may further have at least one hole(s) 180 wherein attacher(s) 130 is removably insertable through hole(s) 180 in at least one skid device and through hole(s) in a housing of snow blower machine 110 such that at least one skid(s) 120 is removably attached to snow blower machine 110. Attacher(s) 130 are located so as to be attachable to the bottom and sides of the housing and are located horizontally rather than vertically to provide height adjustment along the length of the housing (such that skid(s) 120 may be inclined from front to back or vice-versa—according to attacher 130 placement). Further, wheels are not used in the present design. Attachers 130 may be orientated horizontally along the housing of snow blower machine 110 and may be located underneath as well for greater structural stability. Attacher(s) 130 may comprise bolt fasteners 135 but in some embodiments may be a shaft with through-hole wherein a ring-pin may be inserted through shaft and biasly coupled thereby. Other suitable screws and bolt fasteners 135 may be used to mount and secure each skid(s) 120 to snow blower machine 110 skid pad located on the underside of the snow blower machine 110. In this manner, snow blower machine 110 may be raised approximately 2″ higher and provide a slight elevation means for snow blower machine 110 while in use which may facilitate a smoother operation of snow blower machine 110. The thickness of skid(s) 120 (skid-plate) comprises a clearance between rotary auger 112 and hard planar surface 140 allowing for a minimum suitable distance between rotary auger 112 and hard planar surface 140. Skid(s) 120 may be constructed of aluminum or a ferrous material, or skid(s) 120 may be constructed of a composite material resistant to brittle fracture.

Universal snow blower sled systems 100 may be sold as kit 200 comprising the following parts: at least one attacher(s) 130; at least one skid(s) 120; and a set of user-instructions for installation and use.
